We use Percona XtraDB Cluster for MySQL master-master replication. If the cluster goes into split brain mode and every node is non-Primary, the following error is triggered:
SQLSTATE[08S01]: Communication link failure: 1047 WSREP has not yet prepared node for application useMost of the time this is resolved quickly, but using the database driver will get stuck as it doesn't retry the connection.
This PR adds that specific error to the retry connection logic.
